7 June 2018 - Peter Cochrane (University of Suffolk) - Self Awareness: The Next BIG Breakthrough in NLP
For >50 years the dream of talking to a machine at a (human) conversational level has always been 30 years in the future. However, recent advances in computer, sensor, network, robotic, and mobile device hardware has brought that horizon much closer. In short; transistor density and connectivity per chip, along with network complexity crossed a critical threshold and accelerated the abilities of AI.
We know that NLP is critically dependent on context and cognition, plus the most vital element - self-awareness; and whilst context is easily established, cognition, and even more so ‘self-awareness’ remain hotly debated and in the future.
Here we present an entropic quantification of AI which is intuitively extended to AL and life in general. Self-awareness is then identified as an emergent property which we attempt to place on a realistic time-line.
22 March 2018 - Marco Damonte (University of Edinburgh) - Natural Language Understanding with Abstract Meaning Representation
Abstract meaning representation (Banarescu et al, 2013), or AMR for short, is a semantic representation that provides sentences with a deep semantic interpretation. AMR includes most of the shallow-semantic NLP tasks that are usually addressed separately, such as named entity recognition, semantic role labeling and coreference resolution. AMR is not an interlingua, but AMR graphs can be exploited for a number of NLP tasks such as machine translation, summarisation and paraphrasing. Text-to-AMR (parsing) and AMR-to-text (generation) is however far from providing and using sufficiently accurate graphs for downstream applications. Moreover, not much work has been carried out on AMR for languages other than English. In this talk I’ll present my work on addressing these issues.
1 March 2018 - Wang Ling (Google DeepMind)
1 February 2018 - Johannes Welbl (University College London) - Constructing Datasets for Multi-hop Reading Comprehension Across Documents
Contemporary Reading Comprehension (RC) datasets — SQuAD, TriviaQA, etc. — are dominated by queries that can be answered with a single paragraph or document. However, enabling models to combine pieces of textual information from different sources would drastically extend the scope of RC. In this talk, I will introduce a novel Multi-hop RC task, where a model has to learn how to find and combine disjoint pieces of textual evidence, effectively performing multi-step (alias multi-hop) inference.
I present two datasets, WikiHop and MedHop, from different domains — both constructed using a unified methodology. I will then discuss the behaviour of several baseline models, including two established end-to-end RC models, BiDAF and FastQA. For example, one model is in fact capable of integrating information across documents, but both models struggle to select relevant information.
Overall the end-to-end models outperform multiple baselines, but their best accuracy is still far behind human performance, leaving ample room for model improvement. It is our hope that these new datasets will drive future RC model development, leading to new and improved applications in areas such as Search, Question Answering, and Fact Checking.
18 January 2018 - Horacio Saggion (Universitat Pompeu Fabra) - Mining and Enriching Scientific Text Collections
In the current online Open Science context, scientific datasets and tools for deep text analysis, visualization and exploitation play a major role. I will present a system developed over the past three years for “deep” analysis and annotation of scientific text collections. After a brief overview of the system and its main components, I will present our current work on the development of a bi-lingual (Spanish and English) fully annotated text resource in the field of natural language processing that we have created with our system. Moreover, a faceted-search and visualization system to explore the created resource will be also discussed.
I will take the opportunity to present further areas of research carried out in our Natural Language Processing group.
7 December 2017 - Miquel Espla-Gomis (Universitat d'Alacant) - Identifying insertion positions in word-level machine translation quality estimation
Machine translation (MT) quality estimation (QE) is the task of predicting the quality of a translation produced by an MT system without having a reference translation. At the level of sentences, quality is usually estimated in terms of the effort required to fix the translation, trying to predict metrics such as translation error rate (TER) or post-editing time. When it comes to word level, QE is usually tackled as the task of identifying which words in the translation need to be replaced or deleted. The main advantage of word-level MT QE in front of MT sentence- or document-level MT QE is that it can be used to help post-editors to focus their attention on those parts of the translation that need to be fixed. However, with the current approach of only identifying the words that need to be fixed, post-editors using word-level MT QE could be disregarding missing words. In order to improve the performance of such systems, we propose an approach capable to identifying both the words that need to be deleted and the positions where one or more words need to be inserted. The work presented compares different types of simple neural network architectures that build on different sources of bilingual information in order to provide such predictions. The results obtained not only confirm the feasibility of the approach proposed, but also that a reasonably high performance on both tasks can be obtained using relatively simple architectures.

In spite of this surge in interest, very little work bases itself in the social scientific theories on abusive language. In addition, little work deals with the social contexts surrounding abusive statements or bridging the gaps that are introduced by switching to different social contexts.
9 November 2017 - Yorick Wilks (University of Sheffield / Florida Institute for Human & Machine Cognition) - Will there be superintelligence and would it hate us?
The paper examines Bostrom’s notion of Superintelligence and argues that, although we should not be sanguine about the future of AI or its potential for harm, superintelligent AI is highly unlikely to come about in the way Bostrom imagines.
2 November 2017 - Emem Rita Usanga (Bnkability) - Rethinking how deals investment is raised in Africa using NLP
With a $100bn annual infrastructure funding deficit over the next 10years and a npopulation anticipated to double by 2045, the need for infrastructure across the African continent is a pressing need. Government acknowledge this can only be done in partnership with private investors. Problem - international private investor often argue there's a lack of bankable projects in Africa.
The issue of bankability, in other words investability, is one that Bnkability aims to solve using NLP to identify and design bankable projects. Some of the key challenges we face include:
- How do you take knowledge based information and turn into data that a machine can assess uploaded project information against?
- How does a machine identify missing elements within a project plan, so not simply a word but sections for instance risk mitigation?
- And even if it is present, how does it assess how robust the risk mitigation strategy is against sector, country and environmental factors?
This is an interactive session where we present our challenges in the application of NLP to our business solution and attendees propose possible solutions.
26 October 2017 - NLP Student Talks
Chiraag Lala - Multimodal Lexical Translation
Inspired by the tasks of Multimodal Machine Translation and Visual Sense Disambiguation we introduce a task called Multimodal Lexical Translation (MLT). The aim of this new task is to correctly translate an ambiguous word given its context - an image and a sentence in the source language. To facilitate the task, we introduce the MLT datasets, where each data point is a $4$-tuple consisting of an ambiguous source word, its visual context (an image), its textual context (a source sentence), and its translation that conforms with the visual and textual contexts. The dataset has been created from the Multi30K corpus using word-alignment followed by human inspection for English to German and English to French language directions. These datasets form a very valuable multimodal and multilingual language resource with several potential uses including evaluation of lexical disambiguation within (Multimodal) Machine Translation systems.
Fernando Manchego - Sentence Simplification via Sequence Labeling
Text Simplification aims to modify the content and structure of a text, in order to make it easier to read and understand. At the sentence-level, several rewriting operations can be performed to achieve this goal: replacing complex words or phrases for simpler synonyms, deleting unimportant content, splitting the sentence, etc. Most research treats sentence simplification as machine translation (MT), with complex and simple as source and target languages, respectively. In this talk, we will first present an in-depth analysis on the potential and limitations of end-to-end MT-style models using automatic and manual evaluations. To deal with some of the identified problems, we devise a two-step sequence labeling method: (i) identify the simplification operations that need to be performed (if any) in each token of sentence, and (ii) execute the operation using transformation-specific strategies. We show that this operation-based approach is able to produce simpler texts than end-to-end models.
19 October 2017 - Kris Cao (University of Cambridge) - Latent variable models of language
Behind the observed surface form of language exist underlying structures and themes, such as syntax, topic and utterance intent. In this talk, I will present some work which composes graphical models to learn underlying variables with powerful data likelihood functions to model the observed surface form. One such application is in open-domain dialogue modelling, where the latent variables capture the variation in the possible responses to a user utterance. We show that the latent variable approach generates more acceptable diverse output, as measured by human annotators. Another is extending topic models to instead learn topics underlying entire sentences, rather than just words. This lets the model learn topics which capture compositional meaning, which a standard word-level model has difficult doing.
12 October 2017 - Sasha Narayan (University of Edinburgh) - Text-to-text Generation Beyond Machine Translation
In recent years we have witnessed the achievements of sequence-to-sequence encoder-decoder models for machine translation.
It is no surprise that these models are also setting a trend in various other generation tasks such as dialogue generation, image caption generation, sentence compression, paraphrase generation, sentence simplification and document summarization. Yet, these deep learning sequence models are often applied off-the-shelf to these text-to-text generation tasks, not tailoring the underlying model to the specific task to improve performance.
In this talk I will discuss two examples, sentence simplification and document summarization, that explore the hypothesis that tailoring the model with knowledge of the task structure and linguistic requirements leads to better performance. In the first part, I will propose a new sentence simplification task (split-and-rephrase) where the aim is to split a complex sentence into a meaning preserving sequence of shorter sentences. I will show that the semantically-motivated split model is a key factor in generating fluent and meaning preserving rephrasings.
In the second part, I will discuss the shortcomings of sequence-to-sequence abstractive methods for document summarization and show that an extractive summarization system trained to globally optimize a common summarization evaluation metric outperforms state-of-the-art extractive and abstractive systems in both automatic and extensive human evaluations.
BIO: Shashi Narayan is a postdoctoral researcher in the School of Informatics at the University of Edinburgh. He obtained his PhD in Computer Science at the University of Lorraine, INRIA under Claire Gardent in 2014. His research focuses on natural language generation and understanding with an aim to develop general frameworks for generation from underlying meaning representation or for text rewriting such as summarization, text simplification and paraphrase generation. He also has experience with parsing and other structured prediction problems.
4 September 2017 - Thushari Atapattu (University of Adelaide) - Disclosure Analysis of Educational Big Data
Discourse analysis within the educational context consists of processing natural language data generated from learning and teaching processes including written assessments, transcripts, discussion forums, and micro blogs. Computational approaches for discourse analysis integrates NLP with psychological theories of social interaction, discourse comprehension, and communication. Discourse analysis is a complex problem, particularly within massive classrooms (e.g. Massive Open Online Courses – MOOCs). In this talk, I will discuss two of our research in understanding the academic discourse of lecturers as well as learner-generated discourse in MOOCs. Our work aims to detect the learners’ video interactions patterns and inform us of the influence of quality of lecturers’ discourse. This work analyses millions of video interactions in two MOOCs and found that transition in discourse (i.e. lexical diversity, connectivity) impacts on learners’ video engagement behaviour. Further, I will talk about the association between the quality of learner-generated discourse (i.e. discussion posts) and its impact on learning success. Thus, I will explain how the understanding of discourse enables us to identify the interventions for positive student trajectories.
NLP Reading Group
